Question 250
A controlled SOC test uses Refine the KQL conditions to require corroborating process and file context. Which result validates the specified requirement: A detection based on one very broad regex produces false positives in process command lines?
Explanation
Correct Answer
False-positive samples are excluded without losing the seeded malicious command. This is the result that most directly validates the selected action: Refine the KQL conditions to require corroborating process and file context. It proves the requirement in the scenario rather than a related activity. This scenario concerns: A detection based on one very broad regex produces false positives in process command lines.
Incorrect Answers
An alert tied to a test host confirms query execution, not false-positive behavior. The updated detection must drop the known benign command while still matching the seeded malicious command in a paired test.
“The expired synthetic indicator stops generating matches.” tests A threat-intelligence analytics rule includes stale indicators that no longer apply. It does not demonstrate the target outcome of False-positive samples are excluded without losing the seeded malicious command. in the case described. This scenario concerns: A detection based on one very broad regex produces false positives in process command lines.
“A pilot burst produces the configured number of alerts and incidents.” may be appropriate evidence for A scheduled detection needs to group multiple suspicious events into one incident., but the verification of the current incident must instead show False-positive samples are excluded without losing the seeded malicious command. This scenario concerns: A detection based on one very broad regex produces false positives in process command lines.
